3 Electrical connection
3.3.7 Galvanic isolation
The control electronics, including the inputs and outputs, as well as all control
elements, can be connected to SELV circuits.
The digital output can be connected to SELV or mains potential, without preju-
dicing the electrical isolation arrangements of the other inputs and outputs.
There is no galvanic isolation between the voltage supply of the power section
and the load.
Ensure that the metal case of the furnace or combustion chamber is properly
earthed.
